Question:
The uniform bar AD has a mass of 20 kg. If the attached spring is unstretched when θ = 90°, determine the angle θ for equilibrium. Note that the spring always remains in the vertical position due to the roller guide. Investigate the stability of the bar when it is in the equilibrium position.
